Grundfos UPSe 15-58FRC, 115V, variable speed ECM circulator pump (replaces Grundfos UPS 15-58 FRC)

UPSe is a high-efficiency circulator fitted with an electronically commutated motor (ECM). It has been designed for circulating liquids in heating and cooling systems and offers the highest energy savings on the market.

The pump features a wide range of controls, including constant pressure, proportional pressure, and constant curve, each with three settings, making it suitable for almost any hydronic application. And, the Grundfos GO app’s replacement compatibility check makes it easier than ever to select the right replacement pump.

The new toolless, removeable power connector results in fast and easy installation. Fewer call-backs can be expected due to its robust startup, selfventing ability, and dry-run protection. Troubleshooting is also fast and easy with error codes displayed on the pump interface.

A terminal box with conduit connections is provided for power connection

Key Features And Benefits

Versatile replacement solution

• Suitable replacement for most models on the market.

More flexible installations

• A smaller conduit box helps with installations in small spaces and a toolless lever connector allows wiring outside of the conduit box.

Powerful unblocking feature

• To reduce the risk of blockages, the pump is built with non-magnetic shafts and bearings. Should a blockage occur, the pump will try to shake the rotor loose by shifting between different torque levels.

Intelligent dry-run protection

• To avoid unwanted pump breakdowns caused by dry running, the UPSe includes a built-in dry-run protection feature to stop the pump if water is not detected in the system.

Automatic self-venting

• To avoid unwanted noise and reduced performance, UPSe pumps are self-venting for faster setup and less call-backs.

Intuitive troubleshooting

• To help you quickly identify and overcome problems, UPSe pumps feature a warning and alarm light with specific colors and blinking patterns
